Abstract： Objective： To observe the clinical effect of panax notoginseng combined with conventional modern medical therapy on patients with postoperative cerebral hemorrhage. Methods： A total of 100 patients with postoperative cerebral hemorrhage were randomly divided into the observation group and the control group，50 cases in each group. Patients in the two groups were given diosamine tablets and aspirin enteric- coated tablets， and were given intermittent pneumatic pressurization(IPC) as well as routine nursing measures. Patients in the observation group were additionally given administration of panax notoginseng powder through nasointestinal tube. The course of treatment in both groups was seven days. Before treatment and seven days after treatment， the score of Caprini Risk Assessment Scale was evaluated， and levels of fibrinogen(FIB) and D-dimer(D-D) were detected. The occurrence of pulmonary embolism(PE) and deep vein thrombosis(DVT) within one month after seven days of treatment was recorded，and the occurrence of subcutaneous blood stasis， lower limb swelling and lower limb pain was also recorded. Results： After treatment， the Caprini scores in both groups were decreased when compared with those before treatment(P＜0.01)， and the Caprini score in the observation group was lower than that in the control group(P＜0.01). There was no significant difference being found in the comparison of the incidence of PE(P＞0.05). The incidence of DVT and the total incidence of venous thromboembolism in the observation group were lower than that in the control group(P＜0.05). The incidences of subcutaneous stasis， lower limb swelling and lower limb pain in the observation group were lower than that in the control group，there being no significant difference being found in the comparison between the two groups(P＞0.05). The FIB and D-D levels in both groups were decreased when compared with those before treatment(P＜0.01)，FIB and D-D levels in the observation group were lower than those in the control group(P＜0.01). Conclusion： Based on conventional medical measures， the administration of panax notoginseng powder through noseintestinal tube for patients with postoperative cerebral hemorrhage can reduce hypercoagulability and fibrinolysis，and decrease the risk of venous thromboembolism.
